Building a Lemon Powered Battery That Can Charge the Volkswagen Electric I.D. R Racing Car

Former NASA engineer Mark Rober was challenged by Volkswagen to produce enough electricity to support their fully-electric I.D. R racing car at the Pikes Peak International Hill Climb. Rober teamed up with William Osman and a group of bright kids to complete the challenge with lemons. After finding a lemon-powered method for charging a massive battery from VW, the I.D. R went on to break Pikes Peak’s all-time record.
